Positioning multiple implants with respect to single coordinate system

摘要

A method for preparing a femur and a tibia to receive implants. The method includes mapping location of a femoral guide to a coordinate system using a femoral position sensor mounted to at least one of the femoral guide or another femoral surgical device during preparation of the femur to receive a femoral implant. The method further includes mapping location of a tibial guide to the coordinate system using a tibial position sensor mounted to at least one of the tibial guide or another tibial surgical device during preparation of the tibia to receive a tibial implant.

1. A method for preparing a femur and a tibia to receive implants comprising:
mapping location of a femoral guide to a leg mechanical axis using a femoral position sensor mounted to at least one of the femoral guide or another femoral surgical device during preparation of the femur to receive a femoral implant; determining a tibial mechanical axis; and mapping location of a tibial guide to the leg mechanical axis and the tibial mechanical axis using a tibial position sensor mounted to at least one of the tibial guide or another tibial surgical device during preparation of the tibia to receive a tibial implant.
